This is a really neat project via MatrixOrbital on hackster.io
One of us has an older cat with a kidney condition. While she does not need subcutaneous fluid on a regular basis, she very well might in the future. At this point, though, it has become impossible to travel with her by air since so much time is spent in travel to and from the actual airplane which added to the flight time is a dangerously long period to leave her without water. Like many cats, she can be shown water, but nothing can make her actually drink it. Food – yes, water – no.
It might be possible to load her up with fluids prior to a flight, but the primary idea behind this warmer is to be able to transport her by car. The warmer is built to run on 12V so that it can be plugged into a lighter jack and used on the go.
The plan is to load her up with fluid in the morning and stop frequently to allow her to urinate through the day without the worry that she could become dehydrated.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
